2021 Toyota Highlander — clunk when changing from reverse to drive

Intermittent stuff lies if you only catch it once. Swap the cheap/easy piece first on the 2021 Toyota Highlander and see if the fault moves. That's the branch I'd chase this week. On “clunk when changing from reverse to drive,” that was the fork that mattered for me. Take it or leave it — that's what I'd do. Video is ugly but it shows the hesitation.

Checked the easy stuff on the 2021 Toyota Highlander and found one clue worth chasing before I book a shop. Parking it somewhere I can hear it better next time.

I wouldn't throw parts yet. If a shop can't duplicate it on the 2021 Toyota Highlander, bring a video plus freeze-frame data, not just a story. Save the big job until that test fails. That's the whole play. Your commute and mine probably aren't the same, but the test still applies. Cold start is when I can actually reproduce it.

I'd want a measurement, not a hunch. Loaded-suspension checks on the 2021 Toyota Highlander catch play that a wheels-hanging inspection misses. If the cheap test changes it, stop and reassess. Run the total, not the monthly, before you commit. That's my plan before I call anyone.

OP update: scanned the 2021 Toyota Highlander again and still only have the one pending code, no new lights. Trying not to diagnose from the couch.

This is usually cheaper to test than to guess. If a shop can't duplicate it on the 2021 Toyota Highlander, bring a video plus freeze-frame data, not just a story. Don't erase codes until someone who can help has seen them. Run the total, not the monthly, before you commit. That's coming from doing this as an owner, not a shop. Happens in gear, not in park, for what that's worth.

Ask what changed right before it started. Loaded-suspension checks on the 2021 Toyota Highlander catch play that a wheels-hanging inspection misses. You'll know quickly if you're on the wrong tree. Not gospel, but it saved me a headache. I'll update if anything new shows up.

Log the conditions before you spend. Write temp, speed, and in-gear vs coast when the 2021 Toyota Highlander does it — then decide on parts. That's the branch I'd chase this week. On “clunk when changing from reverse to drive,” that was the fork that mattered for me. Stop there until you know. If it repeats twice more I'll book time.

Start with the test that can prove you wrong. Write temp, speed, and in-gear vs coast when the 2021 Toyota Highlander does it — then decide on parts. Don't erase codes until someone who can help has seen them. If they can't show the line item, I assume it's hiding. I'll update if anything new shows up.

If it were in my driveway, two 2021 Toyota Highlanders can feel identical and have different causes, so measure before you copy someone else's repair. Save the big job until that test fails. That's the sequence I'd use. Might be overthinking it, but I'd rather overthink than overspend.

Ask what changed right before it started. Write temp, speed, and in-gear vs coast when the 2021 Toyota Highlander does it — then decide on parts. If the cheap test changes it, stop and reassess. Stop there until you know. I'm keeping receipts and dates in one folder.
